MEANS OF RETABDING CONVEYEB ROLLS.

Application filed September 25,1926. Serial No. 137,718.

This invention relates to a means of re tarding conveyerrolls to prevent them from too rapidly,- and the constructlon is of particular advantage where packages slide down an inclined chute and then pass upon the conveyer rolls to some other place.

It will be understood by those skilled in the art, that if a package comes upon a series of spinning rollers that it w ll travel very rapidly and may strike other packages standing upon-the rolls with such force as to break them open, and this is especially true where the rolls are used with a long l5 lineof packages, for the first package will strike the rolls when they-are practically at a standstill, the next package willstrike the'rolls slowly but will travela little faster, and if a number of .packages come in successively on the rollers the last p'acka e of the series may travel so fast after striliin the rollers that they will break either e selves or the packages that they happen to strike'which are then standing still. Howzs ever, the grade of slides can be made low enough to cause the packages to travel down them readily and when they strike a standing roll to travel no fasterthan is desirable and at a speed not likely to injure other pack- 0 ages, so that with the present invention means is provided to retard the rolls after apackage has passe thereover, and thereby. prevent the next package from being carried too rapidly against the train of ackages.

the present case this object is attained by inserting a series ofloose weights in the roller. These weights may be a series of small rollers or rregular bodies, but I have found that a plurality of spherical llets such as lead shot, produces the ist result.

. Other objects of the invention will be apparent as the description proceeds. An embodiment of the invention is shown in the accompanying drawings in which the same reference numeral is appliedto the same portlon'throughou't the several figures of the drawings and of which there may be a modificationsr Figure 1=is a perspective view showing a portion of an inclined-slide connected to a substantially horizontalfpiece .of. roller conveyer illustrating .the most common place ofapplication of this roller retarding mech-.

In the horizontal portion of the conveyer there are a plurality of the rollers 4 over which all of the packages pass. These rollers 4 are made of, tubular steel with the ends turned in as indicated at 5 on a receivingbox or collar 6. and into which the ball bearin collar. 7. with its soft jacket 8 is pushed. he balls 9 rest upon a bushing 10 which is pushed.

are ordinarily about four inches in-diameter, by about eighteen inches long, although they may be. of different; sizes depending upon the work to be done, and inside ofeach roller there' is placed about one pound of lead shot as indicated at 13. This lead shot'is about #1 insize, though the precise size used. may vary as may be found convenient. j

In useas each package slides 'down'the steel bottom 3 it strikes the roller section. of the carrier and immediately starts passing thereover, each roller turning with very little necessary force but as soon as the packa e has passed th el'eover the shot immedia brings the'roller to rest, and when ,the next package-strikes the roller it will notbe car- 7 ried over it with undue speed.

What I desire to secure by Letters Patent of the United States is as follows, but modifications may be made in carrying out the invention as shown in the drawing-and in the above particularly described form thereof, within the purview of the annexed claimsi 1.
